I'm interested in controlling some patch parameters according to ambient light but I don't know much about this subject. Are there any ready to plug-in sensors out there? Or do I need to buy one of these phototransistors and plug them to an arduino (or any other kind of interface)? Any tips would be very helpful.
PD: I'm not interested in working with the built-in light sensors of the macbook-pro or any cellphones.
Thanks in advance!
